NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Unaudited)

(In Thousands, Except Share and Per Share Data)

1. Basis of Presentation

The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments except those otherwise described herein) considered necessary for a fair presentation have been included, unless otherwise disclosed. Operating results for the three and six months ended October 4, 2020 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2021.

The Consolidated Condensed Balance Sheet at March 31, 2020 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.

The financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s 2020 Annual Report on Form 10-K (SEC File No. 001-32253), which was filed on June 1, 2020 (the “2020 Annual Report”).

EnerSys (the “Company,”) reports interim financial information for 13-week periods, except for the first quarter, which always begins on April 1, and the fourth quarter, which always ends on March 31. The four quarters in fiscal 2021 end on July 5, 2020, October 4, 2020, January 3, 2021, and March 31, 2021, respectively. The four quarters in fiscal 2020 ended on June 30, 2019, September 29, 2019, December 29, 2019, and March 31, 2020, respectively.

The consolidated condensed financial statements include the accounts of the Company and its wholly-owned subsidiaries and any partially owned subsidiaries that the Company has the ability to control. All intercompany transactions and balances have been eliminated in consolidation.

Recently Adopted Accounting Pronouncements

In June 2016, the FASB, issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326)”: Measurement of Credit Losses on Financial Instruments, which changes the recognition model for the impairment of financial instruments, including accounts receivable, loans and held-to-maturity debt securities, among others. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In contrast to current guidance, which considers current information and events and utilizes a probable threshold, (an “incurred loss” model), ASU 2016–13 mandates an “expected loss” model. The expected loss model: (i) estimates the risk of loss even when risk is remote, (ii) estimates losses over the contractual life, (iii) considers past events, current conditions and reasonable supported forecasts and (iv) has no recognition threshold. The Company adopted the standard effective April 1, 2020 and the adoption did not have a material impact on the Company's operating results, financial position or cash flows. However, the adoption resulted in the modification of the Company's policies for accounts receivable.

The Company estimates the allowance for credit losses in relation to accounts receivable based on relevant qualitative and quantitative information about historical events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported accounts receivable. Subsequent to April 1, 2020, accounts receivable are recorded at amortized cost less an allowance for expected credit losses. The Company maintains an allowance for credit losses for the expected failure or inability of its customers to make required payments. The Company recognizes the allowance for expected credit losses at inception and reassesses quarterly, based on management’s expectation of the asset’s collectability. The allowance is based on multiple factors including historical experience with bad debts, the credit quality of the customer base, the aging of such receivables and current macroeconomic conditions, as well as management’s expectations of conditions in the future. The Company’s allowance for uncollectible accounts receivable is based on management’s assessment of the collectability of assets pooled together with similar risk characteristics. The Company then adjusts the historical credit loss percentage by current and forecasted economic conditions. The Company then includes a baseline credit loss percentage into the historical credit loss percentage for each aging category to reflect the potential impact of the current and economic conditions. Such a baseline calculation will be adjusted further if changes in the economic environment impacts the Company's expectation for future credit losses.

Table of Contents

The following table sets forth the quarterly changes in the Company's allowance for doubtful accounts:

Allowance for doubtful accounts:	Balance at Beginning of Period		Provision for doubtful debts		Write-offs, net of recoveries and other		Balance at End of Period
First quarter ended July 5, 2020	$	15,246	$	96	$	(2,113)	$	13,229
Second quarter ended October 4, 2020	$	13,229	$	86	$	2	$	13,317

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848)”: Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional expedients to ease the financial reporting burdens of the expected market transition from London Interbank Offered Rate (LIBOR) to an alternative reference rate such as Secured Overnight Financing Rate (SOFR). The Company’s agreements with respect to its borrowings already contain comparable alternative reference rates that would automatically take effect upon the phasing out of LIBOR. The Company has adopted the standard and the adoption did not have a material impact on the Company's consolidated financial statements.

Accounting Pronouncements Issued But Not Adopted as of October 4, 2020

In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740)”: Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently assessing the potential impact that the adoption will have on its consolidated financial statements.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions take into account historical and forward looking factors that the Company believes are reasonable, including, but not limited to, the potential impacts arising from the coronavirus pandemic of 2019 (“COVID-19”) and public and private sector policies and initiatives aimed at reducing its transmission. As the extent and duration of the impacts of COVID-19 remain unclear, the Company’s estimates and assumptions may evolve as conditions change. Actual results could differ significantly from those estimates.

Examples of significant estimates include the allowance for credit losses, the recoverability of property, plant and equipment, the incremental borrowing rate for lease liabilities, the recoverability of intangible assets and other long-lived assets, fair value measurements, including those related to financial instruments, goodwill and intangible assets, valuation allowances on tax assets, pension and postretirement benefit obligations, contingencies and the identification and valuation of assets acquired and liabilities assumed in connection with business combinations.

2. Revenue Recognition

The Company's revenues by reportable segments are presented in Note 17.

Service revenues related to the work performed for the Company’s customers by its maintenance technicians generally represent a separate and distinct performance obligation. Control for these services passes to the customer as the services are performed. Service revenues for the second quarter of fiscal 2021 and 2020 amounted to $74,327 and $61,282, respectively. Service revenues for the six months of fiscal 2021 and 2020 amounted to $143,085 and $122,000, respectively.

A small portion of the Company's customer arrangements obligate the Company to create customized products for its customers that require the bundling of both products and services into a single performance obligation because the individual products and services that are required to fulfill the customer requirements do not meet the definition for a distinct performance obligation. These customized products generally have no alternative use to the Company and the terms and conditions of these arrangements give the Company the enforceable right to payment for performance completed to date, including a reasonable profit margin. For these arrangements, control transfers over time and the Company measures progress towards completion by selecting the input or output method that best depicts the transfer of control of the underlying goods and services to the customer for each respective arrangement. Methods used by the Company to measure progress toward completion include labor

Table of Contents

hours, costs incurred and units of production. Revenues recognized over time for the second quarter of fiscal 2021 and 2020 amounted to $35,074 and $33,595, respectively. Revenues recognized over time for the six months of fiscal 2021 and 2020 amounted to $71,176 and $75,090, respectively.

On October 4, 2020, the aggregate transaction price allocated to unsatisfied (or partially unsatisfied) performance obligations was approximately $104,552, of which, the Company estimates that approximately $53,781 will be recognized as revenue in fiscal 2021, $36,990 in fiscal 2022, $12,388 in fiscal 2023, $1,359 in fiscal 2024 and $34 in fiscal 2025.

Any payments that are received from a customer in advance, prior to the satisfaction of a related performance obligation and billings in excess of revenue recognized, are deferred and treated as a contract liability. Advance payments and billings in excess of revenue recognized are classified as current or non-current based on the timing of when recognition of revenue is expected. As of October 4, 2020, the current and non-current portion of contract liabilities were $17,871 and $6,383, respectively. As of March 31, 2020, the current and non-current portion of contract liabilities were $17,342 and $8,356, respectively. Revenues recognized during the second quarter of fiscal 2021 and 2020 that were included in the contract liability at the beginning of the year, amounted to $4,175 and $3,690, respectively. Revenues recognized during the six months of fiscal 2021 and 2020 that were included in the contract liability at the beginning of the year, amounted to $7,641 and $8,157, respectively.

Amounts representing work completed and not billed to customers represent contract assets and were $49,769 and $39,048 as of October 4, 2020 and March 31, 2020, respectively.

The Company uses historic customer product return data as a basis of estimation for customer returns and records the reduction of sales at the time revenue is recognized. At October 4, 2020, the right of return asset related to the value of inventory anticipated to be returned from customers was $4,267 and refund liability representing amounts estimated to be refunded to customers was $7,034.

3. Leases

The Company leases manufacturing facilities, distribution centers, office space, vehicles and other equipment under non-cancellable leases with initial terms typically ranging from 1 to 17 years.

Short term leases with an initial term of 12 months or less are not presented on the balance sheet and expense is recognized as incurred.

The following table presents lease assets and liabilities and their balance sheet classification:

4. Acquisition

NorthStar

In fiscal 2020, the Company completed the acquisition of N Holding, AB (“NorthStar”) for $77,777 in cash consideration and the assumption of $107,018 in debt, which was funded using existing cash and credit facilities. NorthStar, through its direct and indirect subsidiaries, manufactures and distributes thin plate pure lead (TPPL) batteries and battery enclosures. NorthStar has two large manufacturing facilities in Springfield, Missouri. The Company acquired tangible and intangible assets, including trademarks, technology, customer relationships and goodwill. Based on valuations performed, trademarks were valued at $6,000, technology at $19,000, customer relationships at $9,000, and goodwill was recorded at $76,784. As a result of the change in operating and reportable segments discussed in Note 17, goodwill associated with the acquisition of NorthStar has been allocated to the Energy Systems and Specialty segments on a relative fair value basis. The useful lives of technology were estimated at 10 years, customer relationships were estimated at 15 to 18 years and trademarks were estimated at 5 years. Goodwill deductible for tax purposes is $75,436.

During the second quarter of fiscal 2021, the Company finalized the measurement of all provisional amounts recognized in connection with the NorthStar business combination. The purchase accounting adjustments resulted in an increase to goodwill during the current quarter, by $2,996 as a result of finalizing income tax accounting.

6. Fair Value of Financial Instruments

Recurring Fair Value Measurements

The following tables represent the financial assets and (liabilities) measured at fair value on a recurring basis as of October 4, 2020 and March 31, 2020, and the basis for that measurement:

	Total Fair Value Measurement October 4, 2020		Quoted Price in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Lead forward contracts	$	(3,229)	$	—	$	(3,229)	$	—
Foreign currency forward contracts	(213)		—		(213)		—
Total derivatives	$	(3,442)	$	—	$	(3,442)	$	—

Foreign currency forward contracts	1		—		1		—
Total derivatives	$	(2,432)	$	—	$	(2,432)	$	—

The fair values of lead forward contracts are calculated using observable prices for lead as quoted on the London Metal Exchange (“LME”) and, therefore, were classified as Level 2 within the fair value hierarchy, as described in Note 1. Summary of Significant Accounting Policies to the Company's consolidated financial statements included in its 2020 Annual Report.

The fair values for foreign currency forward contracts are based upon current quoted market prices and are classified as Level 2 based on the nature of the underlying market in which these derivatives are traded.

Financial Instruments

The fair values of the Company’s cash and cash equivalents approximate carrying value due to their short maturities.

The fair value of the Company’s short-term debt and borrowings under the Amended Credit Facility (as defined in Note 12), approximate their respective carrying value, as they are variable rate debt and the terms are comparable to market terms as of the balance sheet dates and are classified as Level 2.

In fiscal 2020, the Company issued its 4.375% Senior Notes due 2027 (the “2027 Notes”), with an original face value of $300,000. The Company's 5.00% Senior Notes due 2023 (the “2023 Notes”), with an original face value of $300,000, were issued in April 2015. The fair value of the 2027 Notes and 2023 Notes, (collectively, the “Senior Notes”) represent the trading

values based upon quoted market prices and are classified as Level 2. The 2027 Notes were trading at approximately 102% and 94% of face value on October 4, 2020 and March 31, 2020, respectively. The 2023 Notes were trading at approximately 103% and 97% of face value on October 4, 2020 and March 31, 2020, respectively.

The carrying amounts and estimated fair values of the Company’s derivatives and Senior Notes at October 4, 2020 and March 31, 2020 were as follows:

	October 4, 2020				March 31, 2020
	Carrying Amount		Fair Value		Carrying Amount		Fair Value

(2)The fair value amount of the Senior Notes at October 4, 2020 and March 31, 2020 represent the trading value of the instruments.

7. Derivative Financial Instruments

The Company utilizes derivative instruments to reduce its exposure to fluctuations in commodity prices and foreign exchange rates under established procedures and controls. The Company does not enter into derivative contracts for speculative purposes. The Company’s agreements are with creditworthy financial institutions and the Company anticipates performance by counterparties to these contracts and therefore no material loss is expected.

Derivatives in Cash Flow Hedging Relationships

Lead Forward Contracts

The Company enters into lead forward contracts to fix the price for a portion of its lead purchases. Management considers the lead forward contracts to be effective against changes in the cash flows of the underlying lead purchases. The vast majority of such contracts are for a period not extending beyond one year. At October 4, 2020 and March 31, 2020, the Company has hedged the price to purchase approximately 50.0 million pounds and 35.0 million pounds of lead, respectively, for a total purchase price of $43,228 and $30,078, respectively.

Foreign Currency Forward Contracts

The Company uses foreign currency forward contracts and options to hedge a portion of the Company’s foreign currency exposures for lead, as well as other foreign currency exposures so that gains and losses on these contracts offset changes in the underlying foreign currency denominated exposures. The vast majority of such contracts are for a period not extending beyond one year. As of October 4, 2020 and March 31, 2020, the Company had entered into a total of $23,726 and $34,008, respectively, of such contracts.

In the coming twelve months, the Company anticipates that $2,640 of pretax loss relating to lead and foreign currency forward contracts will be reclassified from AOCI (“Accumulated Other Comprehensive Income”) as part of cost of goods sold. This amount represents the current net unrealized impact of hedging lead and foreign exchange rates, which will change as market rates change in the future, and will ultimately be realized in the Consolidated Condensed Statements of Income as an offset to the corresponding actual changes in lead costs to be realized in connection with the variable lead cost and foreign exchange rates being hedged.

Derivatives not Designated in Hedging Relationships

Foreign Currency Forward Contracts

The Company also enters into foreign currency forward contracts to economically hedge foreign currency fluctuations on intercompany loans and foreign currency denominated receivables and payables. These are not designated as hedging

8. Income Taxes

The Company’s income tax provision consists of federal, state and foreign income taxes. The tax provision for the second quarter of fiscal 2021 and 2020 was based on the estimated effective tax rates applicable for the full years ending March 31, 2021 and March 31, 2020, respectively, after giving effect to items specifically related to the interim periods. The Company’s effective income tax rate with respect to any period may be volatile based on the mix of income in the tax jurisdictions in which the Company operates, change in tax laws and the amount of the Company's consolidated earnings before taxes.

On May 19, 2019, a public referendum held in Switzerland approved the Federal Act on Tax Reform and AHV (Old-Age and Survivors Insurance) Financing (TRAF) as adopted by the Swiss Federal Parliament on September 28, 2018. The Company recorded a deferred tax asset of $22,500 during fiscal 2020 related to the amortizable goodwill. Based on further evaluation with the Swiss tax authority, the Company recorded an additional income tax benefit of $1,883 during the six months of fiscal 2021.

The consolidated effective income tax rates for the second quarter of fiscal 2021 and 2020 were 13.9% and (29.5)% and for the six months of fiscal 2021 and 2020 were 14.6% and (4.0)%, respectively. The rate increase in the second quarter and six months of fiscal 2021 compared to the comparable prior year quarter is primarily due to Swiss tax reform and changes in the mix of earnings among tax jurisdictions.

Foreign income as a percentage of worldwide income is estimated to be 73% for fiscal 2021 compared to 75% for fiscal 2020. The foreign effective tax rates for the six months of fiscal 2021 and 2020 were 10.6% and (2.4)%, respectively. The rate increase compared to the prior year period is primarily due to Swiss tax reform and changes in the mix of earnings among tax

16

Table of Contents

jurisdictions. Income from the Company's Swiss subsidiary comprised a substantial portion of the Company's overall foreign mix of income for both fiscal 2021 and fiscal 2020 and is taxed at an effective income tax rate of approximately 8% and 6%, respectively.

9. Warranty

The Company provides for estimated product warranty expenses when products are sold, with related liabilities included within accrued expenses and other liabilities. As warranty estimates are forecasts that are based on the best available information, primarily historical claims experience, costs of claims may ultimately differ from amounts provided. An analysis of changes in the liability for product warranties is as follows:

	Quarter ended				Six months ended
	October 4, 2020		September 29, 2019		October 4, 2020		September 29, 2019
Balance at beginning of period	$	59,771	$	56,179	$	63,525	$	54,568

10. Commitments, Contingencies and Litigation

Litigation and Other Legal Matters

In the ordinary course of business, the Company and its subsidiaries are routinely defendants in or parties to pending and threatened legal actions and proceedings, including actions brought on behalf of various classes of claimants. These actions and proceedings are generally based on alleged violations of environmental, anticompetition, employment, contract and other laws. In some of these actions and proceedings, claims for substantial monetary damages are asserted against the Company and its subsidiaries. In the ordinary course of business, the Company and its subsidiaries are also subject to regulatory and governmental examinations, information gathering requests, inquiries, investigations, and threatened legal actions and proceedings. In connection with formal and informal inquiries by federal, state, local and foreign agencies, the Company and its subsidiaries receive numerous requests, subpoenas and orders for documents, testimony and information in connection with various aspects of their activities.

European Competition Investigations

Certain of the Company’s European subsidiaries had received subpoenas and requests for documents and, in some cases, interviews from, and have had on-site inspections conducted by, the competition authorities of Belgium, Germany and the Netherlands relating to conduct and anticompetitive practices of certain industrial battery participants. For additional information regarding these matters, see Note 19 - Commitments, Contingencies and Litigation to the consolidated financial statements contained in the Annual Report on Form 10-K for the fiscal year ended March 31, 2020.

The Company settled the Belgian regulatory proceeding in February 2016 by acknowledging certain anticompetitive practices and conduct and agreeing to pay a fine of $1,962, which was paid in March 2016. With respect to the Belgian regulatory matter, during fiscal 2019, the Company paid $2,402 towards certain aspects related to this matter, which are under appeal. As of October 4, 2020 and March 31, 2020, the Company did not have a reserve balance related to these matters.

The precise scope, timing and time period at issue, as well as the final outcome of the investigations or customer claims, remain uncertain. Accordingly, the Company’s estimate may change from time to time, and actual losses could vary.

Environmental Issues

As a result of its operations, the Company is subject to various federal, state, and local, as well as international environmental laws and regulations and is exposed to the costs and risks of registering, handling, processing, storing, transporting, and disposing of hazardous substances, especially lead and acid. The Company’s operations are also subject to federal, state, local and international occupational safety and health regulations, including laws and regulations relating to exposure to lead in the workplace.

The Company is responsible for certain cleanup obligations at the former Yuasa battery facility in Sumter, South Carolina, that predates its ownership of this facility. This manufacturing facility was closed in 2001 and the Company established a reserve for this facility, which was $1,060 as of October 4, 2020 and March 31, 2020. Based on current information, the Company’s management believes this reserve is adequate to satisfy the Company’s environmental liabilities at this facility. This facility is separate from the Company’s current metal fabrication facility in Sumter.

Lead and Foreign Currency Forward Contracts

To stabilize its lead costs and reduce volatility from currency movements, the Company enters into contracts with financial institutions. The vast majority of such contracts are for a period not extending beyond one year. Please refer to Note 7 - Derivative Financial Instruments for more details.

11. Restructuring and other Exit Charges

Restructuring Plans

As disclosed in the Company's Annual Report on Form 10-K for the fiscal year ended March 31, 2020, the Company committed to restructuring plans aimed at improving operational efficiencies across its lines of business. A substantial portion of these plans are complete with an estimated $5,500 remaining to be incurred by the end of fiscal 2021. Restructuring and exit charges for the second quarter and six months of fiscal 2021 by reportable segments are as follows:

	Quarter ended October 4, 2020
	Energy Systems		Motive Power		Specialty		Total
Restructuring charges	$	1,331	$	172	$	—	$	1,503
Exit charges	—		1,509		107		1,616

Exit Charges

During fiscal 2021, the Company committed to a plan to close its facility in Vijayawada, India to align with its strategic vision for the new line of business structure and footprint. The Company recorded exit charges of $1,509, primarily relating to asset write-offs.

During fiscal 2019, the Company committed to a plan to close its facility in Targovishte, Bulgaria, which produced diesel-electric submarine batteries. Management determined that the future demand for batteries of diesel-electric submarines was not sufficient given the number of competitors in the market. Of the estimated total charges of $30,000 for all these actions, the Company had recorded charges amounting to $20,242 in fiscal 2019, relating to severance and inventory and fixed asset write-offs and an additional $5,123 relating to cash and non-cash charges during fiscal 2020. During the six months of fiscal 2021, in keeping with its strategy of exiting the manufacture of batteries for diesel-electric submarines, the Company continued to execute further actions which resulted in a non-material net impact from the cash and non-cash charges.

During the second quarter of fiscal 2020, in keeping with its strategy of exiting the manufacture of batteries for diesel-electric submarines, the Company also sold certain licenses and assets for $2,031 and recorded a net gain of $892, which were reported as other exit charges in our Specialty segment.

During the second quarter of fiscal 2020, the Company also wrote off $5,441 of assets at its Kentucky and Tennessee Motive Power plants, as a result of its strategic product mix shift from traditional flooded batteries to maintenance free lead acid and lithium batteries.

Richmond, Kentucky Plant Fire

In fiscal 2020, a fire broke out in the battery formation area of the Company's Richmond, Kentucky motive power production facility. The Company maintains insurance policies for both property damage and business interruption and are finishing cleanup and repair. The Company is nearing completion of the reconstruction of the facility and estimates that the total claim, including the replacement of inventory and equipment, the cleanup and repairs to the building, as well as the claim for business interruption is approximately $45,000.

In fiscal 2020, the Company recorded $17,037 of write-offs for damages caused to its fixed assets and inventories, as well as for cleanup, asset replacement and other ancillary activities directly associated with the fire and received $12,000 in advances related to its initial claims for recovery from its property and casualty insurance carriers.

During the six months of fiscal 2021, the Company recorded a further charge of $15,316 for cleanup and received $18,144 in advances from the insurance carriers. Accumulated charges relating to the fire through October 4, 2020 were $32,353 and advances received from the property and casualty insurance carriers were $30,144.

The Company also received $10,156 through October 4, 2020, of which $5,156 was recorded in the six months of fiscal 2021 and $5,000 in fiscal 2020, relating to a partial settlement of its claim for business interruption which was recorded as a reduction to cost of goods sold. The Company expects to receive $2,000 in its third quarter of fiscal 2021 which would complete the settlement of its business interruption claim.

2017 Credit Facility and Subsequent Amendment

In fiscal 2018, the Company entered into a credit facility (the “2017 Credit Facility”). The 2017 Credit Facility scheduled to mature on September 30, 2022, initially comprised a $600,000 senior secured revolving credit facility (“2017 Revolver”) and a $150,000 senior secured term loan (“2017 Term Loan”). The Company utilized the borrowings from the 2017 Credit Facility to repay its pre-existing credit facility.

In fiscal 2019, the Company amended the 2017 Credit Facility (as amended, the “Amended Credit Facility”) to fund the Alpha acquisition. The Amended Credit Facility consists of $449,105 senior secured term loans (the “Amended 2017 Term Loan”), including a CAD 133,050 ($99,105) term loan and a $700,000 senior secured revolving credit facility (the “Amended 2017 Revolver”). The amendment resulted in an increase of the 2017 Term Loan and the 2017 Revolver by $299,105 and $100,000, respectively.

As of October 4, 2020, the Company had $53,000 outstanding under the Amended 2017 Revolver and $393,665 under the Amended 2017 Term Loan.

Subsequent to the amendment, the quarterly installments payable on the Amended 2017 Term Loan are $5,645 beginning December 31, 2018, $8,468 beginning December 31, 2019 and $11,290 beginning December 31, 2020 with a final payment of $320,000 on September 30, 2022. The Amended Credit Facility may be increased by an aggregate amount of $325,000 in revolving commitments and / or one or more new tranches of term loans, under certain conditions. Both the Amended 2017 Revolver and the Amended 2017 Term Loan bear interest, at the Company's option, at a rate per annum equal to either (i) the London Interbank Offered Rate (“LIBOR”) or Canadian Dollar Offered Rate (“CDOR”) plus (i) LIBOR plus between 1.25% and 2.00% (currently 1.50% and based on the Company's consolidated net leverage ratio) or (ii) the U.S. Dollar Base Rate (which equals, for any day a fluctuating rate per annum equal to the highest of (a) the Federal Funds Effective Rate plus 0.50%, (b) Bank of America “Prime Rate” and (c) the Eurocurrency Base Rate plus 1%; provided that, if the Base Rate shall be less than zero, such rate shall be deemed zero) (iii) the CDOR Base Rate equal to the higher of (a) Bank of America “Prime Rate” and (b) average 30-day CDOR rate plus 0.50%. Obligations under the Amended Credit Facility are secured by substantially all of the Company’s existing and future acquired assets, including substantially all of the capital stock of the Company’s United States subsidiaries that are guarantors under the Amended Credit Facility and up to 65% of the capital stock of certain of the Company’s foreign subsidiaries that are owned by the Company’s United States subsidiaries.

The Amended Credit Facility allows for up to two temporary increases in the maximum leverage ratio from 3.50x to 4.00x for a four quarter period following an acquisition larger than $250,000. Effective December 7, 2018 through December 28, 2019, the maximum leverage ratio was increased to 4.00x. On December 29, 2019, the maximum leverage ratio returned to 3.50x.

The current portion of the Amended 2017 Term Loan of $44,990 is classified as long-term debt as the Company expects to refinance the future quarterly payments with revolver borrowings under the Amended Credit Facility.

Short-Term Debt

As of October 4, 2020 and March 31, 2020, the Company had $31,813 and $46,544, respectively, of short-term borrowings. The weighted average interest rate on these borrowings was approximately 2% at October 4, 2020 and 3% at March 31, 2020.

17. Business Segments

Effective April 1, 2020, the Company's chief operating decision maker, or CODM (the Company's Chief Executive Officer), changed the manner in which he reviews financial information for purposes of assessing business performance and allocating resources, by focusing on the lines of business on a global basis, rather than on geographic basis. As a result of this change, the Company re-evaluated the identification of its operating segments and reportable segments and identified the following as its three new operating segments, based on lines of business:

•Energy Systems - uninterruptible power systems, or “UPS” applications for computer and computer-controlled systems, as well as telecommunications systems, switchgear and electrical control systems used in industrial facilities and electric utilities, large-scale energy storage and energy pipelines. Energy Systems also includes highly integrated power solutions and services to broadband, telecom, renewable and industrial customers, as well as thermally managed cabinets and enclosures for electronic equipment and batteries.

•Motive Power - power for electric industrial forklifts used in manufacturing, warehousing and other material handling applications, as well as mining equipment, diesel locomotive starting and other rail equipment; and

•Specialty - premium starting, lighting and ignition applications in transportation, energy solutions for satellites, military aircraft, submarines, ships and other tactical vehicles, as well as medical and security systems.

The new operating segments also represent the Company's reportable segments under ASC 280, Segment Reporting. All prior comparative periods presented have been recast to conform to these changes.

Summarized financial information related to the Company's reportable segments for the second quarter and six months ended October 4, 2020 and September 29, 2019, is shown below:

18. Subsequent Events

On November 10, 2020, the EnerSys’ Board of Directors approved a plan to substantially close its facility in Hagen, Germany, which produces flooded motive power batteries for forklifts. EnerSys expects to incur a pre-tax charge of approximately $82,000 under this plan when completed, the majority of which is expected to be recorded by the end of fiscal 2021, of which $20,000 is expected to be a non-cash charge from inventory and equipment write-offs. Cash charges include severance, clean up and decommissioning related to the facility, contractual releases and legal expenses.

Management determined that future demand for the motive power batteries produced at this facility was not sufficient, given the conversion from flooded to maintenance free batteries by customers, the existing number of competitors in the market as well as the near term decline in demand and increased uncertainty from the ongoing pandemic.

In connection with this restructuring plan, which is estimated to be substantially complete in fiscal 2022, EnerSys estimates that there will be a reduction of approximately 200 employees.

On November 10, 2020, the Board of Directors approved a quarterly cash dividend of $0.175 per share of common stock to be paid on December 31, 2020, to stockholders of record as of December 18, 2020.

In the following discussion and analysis of results of operations and financial condition, certain financial measures may be considered “non-GAAP financial measures” under SEC rules. These rules require supplemental explanation and reconciliation, which is provided in this Quarterly Report on Form 10-Q. EnerSys’ management uses the non-GAAP measures “primary working capital” and “primary working capital percentage” in its evaluation of cash flow and financial position performance. These disclosures have limitations as an analytical tool, should not be viewed as a substitute for cash flow determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of the Company’s results as reported under GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Management believes that this non-GAAP supplemental information is helpful in understanding the Company’s ongoing operating results.

Overview

EnerSys (the “Company,” “we,” or “us”) is a world leader in stored energy solutions for industrial applications. We also manufacture and distribute energy systems solutions and motive power batteries, specialty batteries, battery chargers, power equipment, battery accessories and outdoor equipment enclosure solutions to customers worldwide. Energy Systems which combine enclosures, power conversion, power distribution and energy storage are used in the telecommunication and broadband, utility industries, uninterruptible power supplies, and numerous applications requiring stored energy solutions. Motive Power batteries and chargers are utilized in electric forklift trucks and other industrial electric powered vehicles. Specialty batteries are used in aerospace and defense applications, large over the road trucks, premium automotive and medical. We also provide aftermarket and customer support services to over 10,000 customers in more than 100 countries through a network of distributors, independent representatives and our internal sales force around the world.

During the first quarter of fiscal 2021, the Company's chief operating decision maker, or CODM (the Company's Chief Executive Officer), changed the manner in which he reviews financial information for purposes of assessing business performance and allocating resources, by focusing on the lines of business on a global basis, rather than on geographic basis. As a result of this change, the Company re-evaluated the identification of its operating segments and reportable segments. The new operating segments were identified as Energy Systems, Motive Power and Specialty. The Company’s operating segments also represent its reportable segments under ASC 280, Segment Reporting. Therefore, the Company has changed its segment presentation from three reportable segments based on geographic basis to three reportable segments based on line of business. All prior comparative periods presented have been recast to reflect these changes.

The Company's three reportable segments, based on lines of business, are as follows:

•Energy Systems - uninterruptible power systems, or “UPS” applications for computer and computer - controlled systems, as well as telecommunications systems, switchgear and electrical control systems used in industrial facilities and electric utilities, large-scale energy storage and energy pipelines. Energy Systems also includes highly integrated power solutions and services to broadband, telecom, renewable and industrial customers, as well as thermally managed cabinets and enclosures for electronic equipment and batteries.

30

Table of Contents

•Motive Power - power for electric industrial forklifts used in manufacturing, warehousing and other material handling applications as well as mining equipment, diesel locomotive starting and other rail equipment; and

•Specialty - premium starting, lighting and ignition applications in transportation, energy solutions for satellites, military aircraft, submarines, ships and other tactical vehicles as well as medical and security systems.

Economic Climate

The COVID-19 pandemic has weakened economic activity around the world. EnerSys’ lines of business have been affected by varying degrees. Our Motive Power business has been our most impacted segment as many industrial manufacturing plants around the world were closed or operated on reduced production levels. During our second fiscal quarter more countries relaxed pandemic restrictions which led to increased economic activity. Our recent order intake reflects this trend and has returned close to pre COVID-19 levels.

Our Energy Systems business has been less impacted as telecommunications and broadband operators either harden their networks to make them more robust or increase bandwidth to handle the increased demand for remote data caused by the work and school from home initiatives. While the pandemic may have caused a delay in full scale deployment of 5G telecom networks, we are seeing a number of companies starting their 5G deployments and feel the pandemic has reinforced the need for 5G.

Within the Specialty business, the truck original equipment manufacturer (OEM) market is recovering from a normal business cycle decline while aftermarket retail and distribution continue to drive increased demand. Defense activity also remains steady.

Volatility of Commodities and Foreign Currencies

Our most significant commodity and foreign currency exposures are related to lead and the Euro, respectively. Historically, volatility of commodity costs and foreign currency exchange rates have caused large swings in our production costs. As a result of the COVID-19 pandemic and a forecasted global economic recession, we anticipate that our commodity costs will be lower in the near future and foreign currency exposures may continue to fluctuate as they have in the past several years. Since the outbreak of COVID-19 in our fourth fiscal quarter of fiscal 2020, we experienced declining commodity costs in our first fiscal quarter followed by a partial price recovery during our second fiscal quarter.

Customer Pricing

Our selling prices fluctuated during the last several years to offset the volatile cost of commodities. Approximately 30% of our revenue is currently subject to agreements that adjust pricing to a market-based index for lead. Selling prices rose for the most part of fiscal 2018 in response to increased lead and other commodity costs, peaked in the first quarter of fiscal 2019 and then declined sequentially in every quarter in fiscal 2019. In fiscal 2020, our selling prices continued to decline in response to declining commodity costs, including lead. Based on current commodity markets, we will likely see continued year over year benefits in fiscal 2021 from declining commodity costs, with some related reduction in our selling prices.

Liquidity and Capital Resources

We believe that our financial position is strong and we have substantial liquidity to cover short-term liquidity requirements and anticipated growth in the foreseeable future, with $414 million of available cash and cash equivalents and available and undrawn credit lines of approximately $766 million at October 4, 2020, availability subject to Credit Agreement financial covenants.

A substantial majority of the Company’s cash and investments are held by foreign subsidiaries and are considered to be indefinitely reinvested and expected to be utilized to fund local operating activities, capital expenditure requirements and acquisitions. The Company believes that it has sufficient sources of domestic and foreign liquidity.

We believe that our strong capital structure and liquidity affords us access to capital for future acquisition and stock repurchase opportunities and continued dividend payments.

Results of Operations

Net Sales

Net sales decreased $53.7 million or 7.1% in the second quarter of fiscal 2021 as compared to the second quarter of fiscal 2020. This decrease was the result of an 11% decrease in organic volume resulting from the pandemic and a 1% decrease in pricing, partially offset by a 4% increase from the NorthStar acquisition and a 1% increase in foreign currency translation impact.

31

Table of Contents

Net sales decreased $129.0 million or 8.4% in the six months of fiscal 2021 as compared to the six months of fiscal 2020. This decrease was the result of an 11% decrease in organic volume resulting from the pandemic and a 1% decrease in pricing, partially offset by a 4% increase from the NorthStar acquisition.

Net sales of our Energy Systems segment in the second quarter of fiscal 2021 decreased $2.1 million or 0.6% compared to the second quarter of fiscal 2020. This decrease was due to a 5% decrease in organic volume and a 1% decrease in pricing, partially offset by a 4% increase from the NorthStar acquisition and a 1% increase in foreign currency translation impact. Demand from telecommunication and data center customers continued to remain strong in a work from home environment, offset by weakness in demand for power supplies from broadband customers. Net sales in the six months of fiscal 2021 decreased $2.5 million or 0.4% compared to the six months of fiscal 2020 primarily due to a 4% decrease in organic volume and a 1% decrease in pricing, offset by a 5% increase from the NorthStar acquisition.

Net sales of our Motive Power segment in the second quarter of fiscal 2021 decreased by $71.5 million or 21.3% compared to the second quarter of fiscal 2020. This decrease was primarily due to a 21% decrease in organic volume and a 1% decrease in pricing, partially offset by a 1% increase in foreign currency translation impact. COVID-19 restrictions and related economic slowdown impacted this segment more than our other lines of business. Net sales in the six months quarter of fiscal 2021 decreased by $153.1 million or 22.5% compared to the six months of fiscal 2020 primarily due to a 21% decrease in organic volume, a 1% decrease each in foreign currency translation impact and pricing.

Net sales of our Specialty segment in the second quarter of fiscal 2021 increased by $19.9 million or 23.8% compared to the second quarter of fiscal 2020. The increase was primarily due to a 17% increase from the NorthStar acquisition, a 9% increase in organic volume and a 1% increase in foreign currency translation impact, partially offset by a 3% decrease in pricing. Net sales in the six months quarter of fiscal 2021 increased by $26.6 million or 16.1% compared to the six months of fiscal 2020 primarily due to a 14% increase from the NorthStar acquisition and a 4% increase in organic volume, partially offset by a

2% decrease in pricing. Increased demand from new aftermarket customers in the automotive battery market generated the significant improvement in revenues in this segment.

Operating expenses, as a percentage of sales, decreased 60 basis points and 20 basis points in the second quarter and six months of fiscal 2021, respectively, compared to the comparable periods of fiscal 2020. We continued to focus on certain austerity measures that were initiated during the aftermath of the COVID-19 outbreak in the first quarter of fiscal 2021. We also benefited from limited travel and other selling expenses, due to the restrictions brought about by COVID-19, allowing us to align our operating expenses with sales volume.

Selling expenses, our main component of operating expenses, were 42.2% and 42.5% of total operating expenses in the second quarter and six months of fiscal 2021, respectively, compared to 44.3% and 44.7% of total operating expenses in the second quarter and six months of fiscal 2020, respectively.

Restructuring and Other Exit Charges

Included in our second quarter of fiscal 2021 operating results are restructuring charges of $1.3 million in Energy Systems, primarily relating to Alpha and $0.2 million in Motive Power. During the second quarter of fiscal 2021, we also committed to a plan to close our facility in Vijayawada, India to align with the strategic vision for our new line of business structure and footprint. We recorded exit charges of $1.5 million primarily relating to asset write-offs.

Table of Contents

Included in our second quarter of fiscal 2020 operating results were restructuring charges of $0.6 million in Energy Systems and $0.4 million in Motive Power, related to improving operational efficiencies in the respective lines of business. Also included in the second quarter of fiscal 2020 operating results were non-cash exit charges of $0.7 million in the Specialty segment relating to the closure of our facility in Targovishte, Bulgaria.

In keeping with our strategy of exiting the manufacture of batteries for diesel-electric submarines, during the second quarter of fiscal 2020, we sold certain licenses and assets for $2.0 million and recorded a net gain of $0.9 million, which was reported as other exit charges in our Specialty segment.

During the second quarter of fiscal 2020, we also wrote off $5.5 million of assets at our Kentucky and Tennessee Motive Power plants, as a result of our strategic product mix shift from traditional flooded batteries to maintenance free lead acid and lithium batteries.

Richmond, Kentucky Plant Fire

In fiscal 2020, a fire broke out in the battery formation area of the Company's Richmond, Kentucky motive power production facility. The Company maintains insurance policies for both property damage and business interruption and are finishing cleanup and repair. The Company is nearing completion of the reconstruction of the facility and estimates that the total claim, including the replacement of inventory and equipment, the cleanup and repairs to the building, as well as the claim for business interruption is approximately $45 million.

In fiscal 2020, the Company recorded $17.0 million of write-offs for damages caused to its fixed assets and inventories, as well as for cleanup, asset replacement and other ancillary activities directly associated with the fire and received $12.0 million in advances related to its initial claims for recovery from its property and casualty insurance carriers.

During the six months of fiscal 2021, the Company recorded a further charge of $15.3 million for cleanup and received $18.1 million in advances from the insurance carriers. Accumulated charges relating to the fire through October 4, 2020 were $32.3 million and advances received from the property and casualty insurance carriers were $30.1 million.

The Company also received $10.2 million through October 4, 2020, of which $5.2 million was recorded in the six months of fiscal 2021 and $5.0 million in fiscal 2020, relating to a partial settlement of its claim for business interruption which was recorded as a reduction to cost of goods sold. We expect to receive an additional $2.0 million in our third fiscal quarter of fiscal 2021, which would complete the settlement of our business interruption claim.

(1) The percentages shown for the segments are computed as a percentage of the applicable segment’s net sales.

Operating earnings decreased $3.3 million or 5.6% and decreased $18.4 or 14.5% in the second quarter and six months of fiscal 2021, respectively, compared to the second quarter and six months of fiscal 2020. Operating earnings, as a percentage of net sales, increased 10 basis points and decreased 50 basis points in the second quarter and six months of fiscal 2021, respectively, compared to the second quarter and six months of fiscal 2020. The relatively flat performance in the current quarter and decline in the six months is primarily due to declines in organic volume, particularly in our Motive Power segment, as explained earlier.

The Energy Systems operating earnings increased 70 basis points and 20 basis points in the second quarter and six months of fiscal 2021, respectively, compared to the second quarter and six months of fiscal 2020. Revenue remained comparable to the prior year as demand for power electronics, batteries and enclosures from telecom operators offset weakness in demand for power supplies from broadband customers. Efficiency declines in manufacturing costs were partially offset by lower commodity costs along with reductions in operating expenses.

The Motive Power operating earnings decreased 110 basis points and 70 basis points in the second quarter and six months of fiscal 2021, respectively, compared to the second quarter and six months of fiscal 2020. Manufacturing efficiency declines from lower volume were partially offset by significant cuts in operating expenses and the receipt of $5.2 million of the business interruption claim relating to the fire at our Richmond, Kentucky plant.

The Specialty operating earnings decreased 90 basis points and 350 basis points in the second quarter and six months of fiscal 2021, respectively, compared to the second quarter and six months of fiscal 2020. While increased demand from new aftermarket customers in the automotive battery market generated significant improvement in revenues, the unfavorable manufacturing variances arising from the NorthStar plants as they transition to EnerSys premium products continued to have a negative impact on the operating earnings.

Interest expense of $9.8 million in the second quarter of fiscal 2021 (net of interest income of $0.5 million) was $0.3 million lower than the interest expense of $10.1 million in the second quarter of fiscal 2020 (net of interest income of $0.6 million).

Interest expense of $20.0 million in the six months of fiscal 2021 (net of interest income of $1.0 million) was $1.0 million lower than the interest expense of 21.0 million in the six months of fiscal 2020 (net of interest income of $1.1 million).

The decrease in interest expense in the second quarter and six months of fiscal 2021 is primarily due to lower average interest rates partially offset by higher average debt. Our average debt outstanding was $1,101.2 million and $1,130.3 million in the second quarter and six months of fiscal 2021, respectively, compared to $1,059.8 million in both the second quarter and six months of fiscal 2020.

Included in interest expense are non-cash charges for deferred financing fees of $0.5 million and $1.0 million in the second quarter and six months of fiscal 2021, respectively, compared to $0.4 million and $0.7 million, in the second quarter and six months of fiscal 2020.

The Company’s income tax provision consists of federal, state and foreign income taxes. The tax provision for the second quarter of fiscal 2021 and 2020 was based on the estimated effective tax rates applicable for the full years ending March 31, 2021 and March 31, 2020, respectively, after giving effect to items specifically related to the interim periods. Our effective income tax rate with respect to any period may be volatile based on the mix of income in the tax jurisdictions in which we operate, change in tax laws and the amount of our consolidated earnings before taxes.

On May 19, 2019, a public referendum held in Switzerland approved the Federal Act on Tax Reform and AHV (Old-Age and Survivors Insurance) Financing (TRAF) as adopted by the Swiss Federal Parliament on September 28, 2018. We recorded a deferred tax asset of $22.5 million during fiscal 2020 related to the amortizable goodwill. Based on further evaluation with the Swiss tax authority, we recorded an additional income tax benefit of $1.9 million during the six months of fiscal 2021.

The consolidated effective income tax rates for the second quarter of fiscal 2021 and 2020 were 13.9% and (29.5)%, respectively, and were 14.6% and (4.0)% for the six months of fiscal 2021 and 2020, respectively. The rate increase in the second quarter and six months of fiscal 2021 compared to the comparable prior year periods is primarily due to Swiss tax reform and changes in the mix of earnings among tax jurisdictions.

Foreign income as a percentage of worldwide income is estimated to be 73% for fiscal 2021 compared to 75% for fiscal 2020. The foreign effective income tax rates for the six months of fiscal 2021 and 2020 were 10.6% and (2.4)%, respectively. The rate increase compared to the prior year period is primarily due to Swiss tax reform and changes in the mix of earnings among tax jurisdictions. Income from the Company's Swiss subsidiary comprised a substantial portion of our overall foreign mix of

income for both fiscal 2021 and fiscal 2020 and is taxed at an effective income tax rate of approximately 8% and 6%, respectively.

Critical Accounting Policies and Estimates

There have been no material changes to our critical accounting policies from those discussed under the caption “Critical Accounting Policies and Estimates” in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2020 Annual Report.

Liquidity and Capital Resources

Cash Flow Analysis

Operating activities provided cash of $217.3 million in the six months of fiscal 2021 compared to $105.1 million in the comparable period of fiscal 2020, with the increase in operating cash resulting primarily from a reduction of $78.1 million in our primary working capital, net of currency translation changes. Primary working capital is discussed in further detail below. In the six months of fiscal 2021, net earnings were $70.9 million, depreciation and amortization $47.1 million, stock-based compensation $10.6 million, non-cash charges relating to exit charges $1.8 million, deferred tax benefit of $1.8 million and non-cash interest of $1.0 million. Prepaid and other current assets provided a source of funds of $7.4 million, primarily from the receipt of $23.1 million towards the insurance receivable relating to the Richmond plant claim in fiscal 2020 and the receipt of a working capital adjustment claim of $2.0 million, relating to an acquisition made several years ago, partially offset by an increase in contract assets of $10.4 million and other prepaid expenses such as taxes and insurance of $7.3 million. Other assets decreased by $3.1 million. Accrued expenses provided a source of funds of $1.3 million primarily from payroll related accruals of $12.5 million, offset by payments of warranty of $4.2 million, freight, tariffs and other expenses of $7.0 million. Other liabilities decreased by $3.0 million primarily relating to income taxes.

In the six months of fiscal 2020, cash provided by operating activities of $105.1 million was primarily from net earnings of $111.3 million, depreciation and amortization of $41.1 million, non-cash charges relating to restructuring, exit and other charges of $10.0 million, stock-based compensation of $8.9 million, provision for doubtful debts of $3.2 million and non-cash interest of $0.8 million, partially offset by deferred taxes of $21.0 million resulting from the Swiss Tax Reform. Cash provided by earnings adjusted for non-cash items were partially offset by the increase in primary working capital of $6.9 million, net of currency translation changes. Accrued expenses decreased by $18.5 million primarily for payments of $7.3 million related to the German competition authority matter and $6.1 million paid to the seller in connection with the Alpha acquisition, for certain reimbursable pre-acquisition items. Prepaid and other current assets increased by $18.2 million, primarily due to contract assets of $8.0 million, $4.0 million receivable from the Seller (Alpha) and insurance receivable of $1.9 million relating to the Richmond plant claim. Other liabilities decreased by $10.0 million due to income taxes.

As explained in the discussion of our use of “non-GAAP financial measures,” we monitor the level and percentage of primary working capital to sales. Primary working capital for this purpose is trade accounts receivable, plus inventories, minus trade accounts payable. The resulting net amount is divided by the trailing three month net sales (annualized) to derive a primary working capital percentage. Primary working capital was $763.7 million (yielding a primary working capital percentage of 27.0%) at October 4, 2020, $833.5 million (yielding a primary working capital percentage of 26.7%) at March 31, 2020 and $815.3 million at September 29, 2019 (yielding a primary working capital percentage of 26.7%). The primary working capital percentage of 27.0% at October 4, 2020 is 30 basis points higher than that for March 31, 2020 and September 29, 2019. The large decrease in primary working capital dollars, compared to the prior year periods reflects the decrease in all the three components of primary working capital, mainly accounts receivable and accounts payable. Sales declined as a direct adverse impact from COVID-19. Lower inventories reflect the Company's lower order levels and concerted efforts to keep inventory levels down.

(1) The Company acquired NorthStar on September 30, 2019, as disclosed in Note 4 to the Consolidated Condensed Financial Statements included in this Quarterly Report on Form 10-Q. Therefore, the primary working capital and related calculations as of September 29, 2019 do not include NorthStar's primary working capital and its components. The inclusion of NorthStar's primary working capital did not have a material impact on the Company's consolidated primary working capital as of October 4, 2020 and March 31, 2020.

Investing activities used cash of $39.8 million in the six months of fiscal 2021 which primarily consisted of capital expenditures relating to plant improvements.

Investing activities used cash of $40.7 million in the six months of fiscal 2020 which primarily consisted of capital expenditures of $43.4 million, relating to plant improvements.

Financing activities used cash of $105.8 million in the six months of fiscal 2021. During the six months of fiscal 2021, we borrowed $45.0 million under the Amended 2017 Revolver and repaid $100.0 million of the Amended 2017 Revolver. Repayment on the Amended 2017 Term Loan was $16.8 million and net payments on short-term debt were $16.5 million. Payment of cash dividends to our stockholders were $14.9 million and payment of taxes related to net share settlement of equity awards were $4.6 million.

Financing activities provided cash of $68.8 million in the six months of fiscal 2020. During the six months of fiscal 2020, we borrowed $285.0 million under the Amended 2017 Revolver and repaid $135.0 million of the Amended 2017 Revolver. Repayment on the Amended 2017 Term Loan was $5.6 million and net payments on short-term debt were $20.0 million. Treasury stock open market purchases were $34.6 million, payment of cash dividends to our stockholders were $14.9 million and payment of taxes related to net share settlement of equity awards were $6.2 million.

Currency translation had a positive impact of $15.6 million and a negative impact of $7.5 million on our cash balance in the six months of fiscal 2021 and the six months of fiscal 2020, respectively. In the six months of fiscal 2021, principal currencies in which we do business such as the Euro, Swiss franc, Polish zloty and British pound generally trended stronger versus the U.S. dollar.

As a result of the above, total cash and cash equivalents increased by $87.3 million to $414.2 million, in the six months of fiscal 2021 compared to an increase by $125.6 million to $424.8 million, in the comparable period of fiscal 2020.

Compliance with Debt Covenants

All obligations under our Amended Credit Facility are secured by, among other things, substantially all of our U.S. assets. The Amended Credit Facility contains various covenants which, absent prepayment in full of the indebtedness and other obligations, or the receipt of waivers, limit our ability to conduct certain specified business transactions, buy or sell assets out of the ordinary course of business, engage in sale and leaseback transactions, pay dividends and take certain other actions. There are no prepayment penalties on loans under this credit facility.

We are in compliance with all covenants and conditions under our Amended Credit Facility and Senior Notes. We believe that we will continue to comply with these covenants and conditions, and that we have the financial resources and the capital available to fund the foreseeable organic growth in our business and to remain active in pursuing further acquisition opportunities. See Note 10 to the Consolidated Financial Statements included in our 2020 Annual Report and Note 12 to the Consolidated Condensed Financial Statements included in this Quarterly Report on Form 10-Q for a detailed description of our debt.

Contractual Obligations and Commercial Commitments

A table of our obligations is contained in Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Contractual Obligations of our 2020 Annual Report for the year ended March 31, 2020. As of October 4, 2020, we had no significant changes to our contractual obligations table contained in our 2020 Annual Report.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risks

Our cash flows and earnings are subject to fluctuations resulting from changes in raw material costs, foreign currency exchange rates and interest rates. We manage our exposure to these market risks through internally established policies and procedures and, when deemed appropriate, through the use of derivative financial instruments. Our policy does not allow speculation in derivative instruments for profit or execution of derivative instrument contracts for which there are no underlying exposures. We do not use financial instruments for trading purposes and are not a party to any leveraged derivatives. We monitor our underlying market risk exposures on an ongoing basis and believe that we can modify or adapt our hedging strategies as needed.

Counterparty Risks

We have entered into lead forward purchase contracts and foreign exchange forward and purchased option contracts to manage the risk associated with our exposures to fluctuations resulting from changes in raw material costs and foreign currency exchange rates. The Company’s agreements are with creditworthy financial institutions. Those contracts that result in a liability position at October 4, 2020 are $3.6 million (pre-tax). Those contracts that result in an asset position at October 4, 2020 are $0.2 million (pre-tax) and the vast majority of these will settle within one year. The impact on the Company due to nonperformance by the counterparties has been evaluated and not deemed material.

Interest Rate Risks

We are exposed to changes in variable U.S. interest rates on borrowings under our credit agreements as well as short-term borrowings in our foreign subsidiaries.

A 100 basis point increase in interest rates would have increased interest expense, on an annualized basis, by approximately $4.8 million on the variable rate portions of our debt.

Commodity Cost Risks – Lead Contracts

We have a significant risk in our exposure to certain raw materials. Our largest single raw material cost is for lead, for which the cost remains volatile. In order to hedge against increases in our lead cost, we have entered into forward contracts with financial institutions to fix the price of lead. A vast majority of such contracts are for a period not extending beyond one year. We had the following contracts outstanding at the dates shown below:

Date	$’s Under Contract (in millions)		# Pounds Purchased (in millions)	Average Cost/Pound		Approximate % of Lead Requirements (1)
October 4, 2020	$	43.2	50.0	$	0.86	9	%
March 31, 2020	30.1		35.0	0.86		6
September 29, 2019	49.9		54.0	0.92		7

(1) Based on approximate annual lead requirements for the periods then ended.

For the remaining two quarters of this fiscal year, we believe approximately 71% of the cost of our lead requirements is known. This takes into account the hedge contracts in place at October 4, 2020, lead purchased by October 4, 2020 that will be reflected in future costs under our FIFO accounting policy, and the benefit from our lead tolling program.

We estimate that a 10% increase in our cost of lead would have increased our cost of goods sold by approximately $13 million and $27 million, respectively, in the second quarter and six months of fiscal 2021.

Foreign Currency Exchange Rate Risks

We manufacture and assemble our products globally in the Americas, EMEA and Asia. Approximately 40% of our sales and expenses are transacted in foreign currencies. Our sales revenue, production costs, profit margins and competitive position are affected by the strength of the currencies in countries where we manufacture or purchase goods relative to the strength of the currencies in countries where our products are sold. Additionally, as we report our financial statements in U.S. dollars, our financial results are affected by the strength of the currencies in countries where we have operations relative to the strength of the U.S. dollar. The principal foreign currencies in which we conduct business are the Euro, Swiss franc, British pound, Polish zloty, Chinese renminbi and Mexican peso.

We quantify and monitor our global foreign currency exposures. Our largest foreign currency exposure is from the purchase and conversion of U.S. dollar based lead costs into local currencies in Europe. Additionally, we have currency exposures from intercompany financing and intercompany and third party trade transactions. On a selective basis, we enter into foreign currency forward contracts and purchase option contracts to reduce the impact from the volatility of currency movements; however, we cannot be certain that foreign currency fluctuations will not impact our operations in the future.

We hedge approximately 5% - 10% of the nominal amount of our known foreign exchange transactional exposures. We primarily enter into foreign currency exchange contracts to reduce the earnings and cash flow impact of the variation of non-functional currency denominated receivables and payables. The vast majority of such contracts are for a period not extending beyond one year.

Gains and losses resulting from hedging instruments offset the foreign exchange gains or losses on the underlying assets and liabilities being hedged. The maturities of the forward exchange contracts generally coincide with the settlement dates of the related transactions. Realized and unrealized gains and losses on these contracts are recognized in the same period as gains and losses on the hedged items. We also selectively hedge anticipated transactions that are subject to foreign exchange exposure, primarily with foreign currency exchange contracts, which are designated as cash flow hedges in accordance with Topic 815 - Derivatives and Hedging.

At October 4, 2020 and September 29, 2019, we estimate that an unfavorable 10% movement in the exchange rates would have adversely changed our hedge valuations by approximately $3.3 million and $3.5 million, respectively.

ITEM 4. CONTROLS AND PROCEDURES

(a) Disclosure Controls and Procedures. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures are effective. We completed the NorthStar acquisition on September 30, 2019, and are in the process, but have not yet concluded our assessment of the effectiveness of our internal control over financial reporting including this recent acquisition. Accordingly, pursuant to the SEC's general guidance that an assessment of a recently acquired business may be omitted from the scope of an assessment in the year of acquisition, the scope of our assessment of the effectiveness of our disclosure controls and procedures does not include NorthStar. NorthStar accounted for 7.5% of total assets as of October 4, 2020 and 4.9% of net sales, in both the second quarter and six months ended October 4, 2020.

(b) Internal Control Over Financial Reporting. The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, evaluated any change in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) and determined that there was no change in our internal control over financial reporting during the quarter to which this report relates that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments except those otherwise described herein) considered necessary for a fair presentation have been included, unless otherwise disclosed. Operating results for the three and six months ended October 4, 2020 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2021.

The Consolidated Condensed Balance Sheet at March 31, 2020 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.

The financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s 2020 Annual Report on Form 10-K (SEC File No. 001-32253), which was filed on June 1, 2020 (the “2020 Annual Report”).

EnerSys (the “Company,”) reports interim financial information for 13-week periods, except for the first quarter, which always begins on April 1, and the fourth quarter, which always ends on March 31. The four quarters in fiscal 2021 end on July 5, 2020, October 4, 2020, January 3, 2021, and March 31, 2021, respectively. The four quarters in fiscal 2020 ended on June 30, 2019, September 29, 2019, December 29, 2019, and March 31, 2020, respectively.

The consolidated condensed financial statements include the accounts of the Company and its wholly-owned subsidiaries and any partially owned subsidiaries that the Company has the ability to control. All intercompany transactions and balances have been eliminated in consolidation.

Recently Adopted Accounting Pronouncements

In June 2016, the FASB, issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326)”: Measurement of Credit Losses on Financial Instruments, which changes the recognition model for the impairment of financial instruments, including accounts receivable, loans and held-to-maturity debt securities, among others. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In contrast to current guidance, which considers current information and events and utilizes a probable threshold, (an “incurred loss” model), ASU 2016–13 mandates an “expected loss” model. The expected loss model: (i) estimates the risk of loss even when risk is remote, (ii) estimates losses over the contractual life, (iii) considers past events, current conditions and reasonable supported forecasts and (iv) has no recognition threshold. The Company adopted the standard effective April 1, 2020 and the adoption did not have a material impact on the Company's operating results, financial position or cash flows. However, the adoption resulted in the modification of the Company's policies for accounts receivable.

The Company estimates the allowance for credit losses in relation to accounts receivable based on relevant qualitative and quantitative information about historical events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported accounts receivable. Subsequent to April 1, 2020, accounts receivable are recorded at amortized cost less an allowance for expected credit losses. The Company maintains an allowance for credit losses for the expected failure or inability of its customers to make required payments. The Company recognizes the allowance for expected credit losses at inception and reassesses quarterly, based on management’s expectation of the asset’s collectability. The allowance is based on multiple factors including historical experience with bad debts, the credit quality of the customer base, the aging of such receivables and current macroeconomic conditions, as well as management’s expectations of conditions in the future. The Company’s allowance for uncollectible accounts receivable is based on management’s assessment of the collectability of assets pooled together with similar risk characteristics. The Company then adjusts the historical credit loss percentage by current and forecasted economic conditions. The Company then includes a baseline credit loss percentage into the historical credit loss percentage for each aging category to reflect the potential impact of the current and economic conditions. Such a baseline calculation will be adjusted further if changes in the economic environment impacts the Company's expectation for future credit losses.

The following table sets forth the quarterly changes in the Company's allowance for doubtful accounts:

Allowance for doubtful accounts:	Balance at Beginning of Period		Provision for doubtful debts		Write-offs, net of recoveries and other		Balance at End of Period
First quarter ended July 5, 2020	$	15,246	$	96	$	(2,113)	$	13,229
Second quarter ended October 4, 2020	$	13,229	$	86	$	2	$	13,317

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848)”: Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional expedients to ease the financial reporting burdens of the expected market transition from London Interbank Offered Rate (LIBOR) to an alternative reference rate such as Secured Overnight Financing Rate (SOFR). The Company’s agreements with respect to its borrowings already contain comparable alternative reference rates that would automatically take effect upon the phasing out of LIBOR. The Company has adopted the standard and the adoption did not have a material impact on the Company's consolidated financial statements.

Accounting Pronouncements Issued But Not Adopted as of October 4, 2020

In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740)”: Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently assessing the potential impact that the adoption will have on its consolidated financial statements.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions take into account historical and forward looking factors that the Company believes are reasonable, including, but not limited to, the potential impacts arising from the coronavirus pandemic of 2019 (“COVID-19”) and public and private sector policies and initiatives aimed at reducing its transmission. As the extent and duration of the impacts of COVID-19 remain unclear, the Company’s estimates and assumptions may evolve as conditions change. Actual results could differ significantly from those estimates.

Examples of significant estimates include the allowance for credit losses, the recoverability of property, plant and equipment, the incremental borrowing rate for lease liabilities, the recoverability of intangible assets and other long-lived assets, fair value measurements, including those related to financial instruments, goodwill and intangible assets, valuation allowances on tax assets, pension and postretirement benefit obligations, contingencies and the identification and valuation of assets acquired and liabilities assumed in connection with business combinations.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Revenue Recognition

The Company's revenues by reportable segments are presented in Note 17.

Service revenues related to the work performed for the Company’s customers by its maintenance technicians generally represent a separate and distinct performance obligation. Control for these services passes to the customer as the services are performed. Service revenues for the second quarter of fiscal 2021 and 2020 amounted to $74,327 and $61,282, respectively. Service revenues for the six months of fiscal 2021 and 2020 amounted to $143,085 and $122,000, respectively.

A small portion of the Company's customer arrangements obligate the Company to create customized products for its customers that require the bundling of both products and services into a single performance obligation because the individual products and services that are required to fulfill the customer requirements do not meet the definition for a distinct performance obligation. These customized products generally have no alternative use to the Company and the terms and conditions of these arrangements give the Company the enforceable right to payment for performance completed to date, including a reasonable profit margin. For these arrangements, control transfers over time and the Company measures progress towards completion by selecting the input or output method that best depicts the transfer of control of the underlying goods and services to the customer for each respective arrangement. Methods used by the Company to measure progress toward completion include labor

hours, costs incurred and units of production. Revenues recognized over time for the second quarter of fiscal 2021 and 2020 amounted to $35,074 and $33,595, respectively. Revenues recognized over time for the six months of fiscal 2021 and 2020 amounted to $71,176 and $75,090, respectively.

On October 4, 2020, the aggregate transaction price allocated to unsatisfied (or partially unsatisfied) performance obligations was approximately $104,552, of which, the Company estimates that approximately $53,781 will be recognized as revenue in fiscal 2021, $36,990 in fiscal 2022, $12,388 in fiscal 2023, $1,359 in fiscal 2024 and $34 in fiscal 2025.

Any payments that are received from a customer in advance, prior to the satisfaction of a related performance obligation and billings in excess of revenue recognized, are deferred and treated as a contract liability. Advance payments and billings in excess of revenue recognized are classified as current or non-current based on the timing of when recognition of revenue is expected. As of October 4, 2020, the current and non-current portion of contract liabilities were $17,871 and $6,383, respectively. As of March 31, 2020, the current and non-current portion of contract liabilities were $17,342 and $8,356, respectively. Revenues recognized during the second quarter of fiscal 2021 and 2020 that were included in the contract liability at the beginning of the year, amounted to $4,175 and $3,690, respectively. Revenues recognized during the six months of fiscal 2021 and 2020 that were included in the contract liability at the beginning of the year, amounted to $7,641 and $8,157, respectively.

Amounts representing work completed and not billed to customers represent contract assets and were $49,769 and $39,048 as of October 4, 2020 and March 31, 2020, respectively.

The Company uses historic customer product return data as a basis of estimation for customer returns and records the reduction of sales at the time revenue is recognized. At October 4, 2020, the right of return asset related to the value of inventory anticipated to be returned from customers was $4,267 and refund liability representing amounts estimated to be refunded to customers was $7,034.

Acquisitions

Acquisition

NorthStar

In fiscal 2020, the Company completed the acquisition of N Holding, AB (“NorthStar”) for $77,777 in cash consideration and the assumption of $107,018 in debt, which was funded using existing cash and credit facilities. NorthStar, through its direct and indirect subsidiaries, manufactures and distributes thin plate pure lead (TPPL) batteries and battery enclosures. NorthStar has two large manufacturing facilities in Springfield, Missouri. The Company acquired tangible and intangible assets, including trademarks, technology, customer relationships and goodwill. Based on valuations performed, trademarks were valued at $6,000, technology at $19,000, customer relationships at $9,000, and goodwill was recorded at $76,784. As a result of the change in operating and reportable segments discussed in Note 17, goodwill associated with the acquisition of NorthStar has been allocated to the Energy Systems and Specialty segments on a relative fair value basis. The useful lives of technology were estimated at 10 years, customer relationships were estimated at 15 to 18 years and trademarks were estimated at 5 years. Goodwill deductible for tax purposes is $75,436.

During the second quarter of fiscal 2021, the Company finalized the measurement of all provisional amounts recognized in connection with the NorthStar business combination. The purchase accounting adjustments resulted in an increase to goodwill during the current quarter, by $2,996 as a result of finalizing income tax accounting.

Recurring Fair Value Measurements

The following tables represent the financial assets and (liabilities) measured at fair value on a recurring basis as of October 4, 2020 and March 31, 2020, and the basis for that measurement:

	Total Fair Value Measurement October 4, 2020		Quoted Price in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Foreign currency forward contracts	1		—		1		—
Total derivatives	$	(2,432)	$	—	$	(2,432)	$	—

The fair values of lead forward contracts are calculated using observable prices for lead as quoted on the London Metal Exchange (“LME”) and, therefore, were classified as Level 2 within the fair value hierarchy, as described in Note 1. Summary of Significant Accounting Policies to the Company's consolidated financial statements included in its 2020 Annual Report.

The fair values for foreign currency forward contracts are based upon current quoted market prices and are classified as Level 2 based on the nature of the underlying market in which these derivatives are traded.

Financial Instruments

The fair values of the Company’s cash and cash equivalents approximate carrying value due to their short maturities.

The fair value of the Company’s short-term debt and borrowings under the Amended Credit Facility (as defined in Note 12), approximate their respective carrying value, as they are variable rate debt and the terms are comparable to market terms as of the balance sheet dates and are classified as Level 2.

In fiscal 2020, the Company issued its 4.375% Senior Notes due 2027 (the “2027 Notes”), with an original face value of $300,000. The Company's 5.00% Senior Notes due 2023 (the “2023 Notes”), with an original face value of $300,000, were issued in April 2015. The fair value of the 2027 Notes and 2023 Notes, (collectively, the “Senior Notes”) represent the trading

values based upon quoted market prices and are classified as Level 2. The 2027 Notes were trading at approximately 102% and 94% of face value on October 4, 2020 and March 31, 2020, respectively. The 2023 Notes were trading at approximately 103% and 97% of face value on October 4, 2020 and March 31, 2020, respectively.

The carrying amounts and estimated fair values of the Company’s derivatives and Senior Notes at October 4, 2020 and March 31, 2020 were as follows:

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

The Company utilizes derivative instruments to reduce its exposure to fluctuations in commodity prices and foreign exchange rates under established procedures and controls. The Company does not enter into derivative contracts for speculative purposes. The Company’s agreements are with creditworthy financial institutions and the Company anticipates performance by counterparties to these contracts and therefore no material loss is expected.

Derivatives in Cash Flow Hedging Relationships

Lead Forward Contracts

The Company enters into lead forward contracts to fix the price for a portion of its lead purchases. Management considers the lead forward contracts to be effective against changes in the cash flows of the underlying lead purchases. The vast majority of such contracts are for a period not extending beyond one year. At October 4, 2020 and March 31, 2020, the Company has hedged the price to purchase approximately 50.0 million pounds and 35.0 million pounds of lead, respectively, for a total purchase price of $43,228 and $30,078, respectively.

Foreign Currency Forward Contracts

The Company uses foreign currency forward contracts and options to hedge a portion of the Company’s foreign currency exposures for lead, as well as other foreign currency exposures so that gains and losses on these contracts offset changes in the underlying foreign currency denominated exposures. The vast majority of such contracts are for a period not extending beyond one year. As of October 4, 2020 and March 31, 2020, the Company had entered into a total of $23,726 and $34,008, respectively, of such contracts.

In the coming twelve months, the Company anticipates that $2,640 of pretax loss relating to lead and foreign currency forward contracts will be reclassified from AOCI (“Accumulated Other Comprehensive Income”) as part of cost of goods sold. This amount represents the current net unrealized impact of hedging lead and foreign exchange rates, which will change as market rates change in the future, and will ultimately be realized in the Consolidated Condensed Statements of Income as an offset to the corresponding actual changes in lead costs to be realized in connection with the variable lead cost and foreign exchange rates being hedged.

Derivatives not Designated in Hedging Relationships

Foreign Currency Forward Contracts

The Company also enters into foreign currency forward contracts to economically hedge foreign currency fluctuations on intercompany loans and foreign currency denominated receivables and payables. These are not designated as hedging

instruments and changes in fair value of these instruments are recorded directly in the Consolidated Condensed Statements of Income. As of October 4, 2020 and March 31, 2020, the notional amount of these contracts was $26,769 and $42,232, respectively.

Income Taxes

Income Taxes

The Company’s income tax provision consists of federal, state and foreign income taxes. The tax provision for the second quarter of fiscal 2021 and 2020 was based on the estimated effective tax rates applicable for the full years ending March 31, 2021 and March 31, 2020, respectively, after giving effect to items specifically related to the interim periods. The Company’s effective income tax rate with respect to any period may be volatile based on the mix of income in the tax jurisdictions in which the Company operates, change in tax laws and the amount of the Company's consolidated earnings before taxes.

On May 19, 2019, a public referendum held in Switzerland approved the Federal Act on Tax Reform and AHV (Old-Age and Survivors Insurance) Financing (TRAF) as adopted by the Swiss Federal Parliament on September 28, 2018. The Company recorded a deferred tax asset of $22,500 during fiscal 2020 related to the amortizable goodwill. Based on further evaluation with the Swiss tax authority, the Company recorded an additional income tax benefit of $1,883 during the six months of fiscal 2021.

The consolidated effective income tax rates for the second quarter of fiscal 2021 and 2020 were 13.9% and (29.5)% and for the six months of fiscal 2021 and 2020 were 14.6% and (4.0)%, respectively. The rate increase in the second quarter and six months of fiscal 2021 compared to the comparable prior year quarter is primarily due to Swiss tax reform and changes in the mix of earnings among tax jurisdictions.

Foreign income as a percentage of worldwide income is estimated to be 73% for fiscal 2021 compared to 75% for fiscal 2020. The foreign effective tax rates for the six months of fiscal 2021 and 2020 were 10.6% and (2.4)%, respectively. The rate increase compared to the prior year period is primarily due to Swiss tax reform and changes in the mix of earnings among tax

jurisdictions. Income from the Company's Swiss subsidiary comprised a substantial portion of the Company's overall foreign mix of income for both fiscal 2021 and fiscal 2020 and is taxed at an effective income tax rate of approximately 8% and 6%, respectively.

Commitments, Contingencies and Litigation

Litigation and Other Legal Matters

In the ordinary course of business, the Company and its subsidiaries are routinely defendants in or parties to pending and threatened legal actions and proceedings, including actions brought on behalf of various classes of claimants. These actions and proceedings are generally based on alleged violations of environmental, anticompetition, employment, contract and other laws. In some of these actions and proceedings, claims for substantial monetary damages are asserted against the Company and its subsidiaries. In the ordinary course of business, the Company and its subsidiaries are also subject to regulatory and governmental examinations, information gathering requests, inquiries, investigations, and threatened legal actions and proceedings. In connection with formal and informal inquiries by federal, state, local and foreign agencies, the Company and its subsidiaries receive numerous requests, subpoenas and orders for documents, testimony and information in connection with various aspects of their activities.

European Competition Investigations

Certain of the Company’s European subsidiaries had received subpoenas and requests for documents and, in some cases, interviews from, and have had on-site inspections conducted by, the competition authorities of Belgium, Germany and the Netherlands relating to conduct and anticompetitive practices of certain industrial battery participants. For additional information regarding these matters, see Note 19 - Commitments, Contingencies and Litigation to the consolidated financial statements contained in the Annual Report on Form 10-K for the fiscal year ended March 31, 2020.

The Company settled the Belgian regulatory proceeding in February 2016 by acknowledging certain anticompetitive practices and conduct and agreeing to pay a fine of $1,962, which was paid in March 2016. With respect to the Belgian regulatory matter, during fiscal 2019, the Company paid $2,402 towards certain aspects related to this matter, which are under appeal. As of October 4, 2020 and March 31, 2020, the Company did not have a reserve balance related to these matters.

The precise scope, timing and time period at issue, as well as the final outcome of the investigations or customer claims, remain uncertain. Accordingly, the Company’s estimate may change from time to time, and actual losses could vary.

Environmental Issues

As a result of its operations, the Company is subject to various federal, state, and local, as well as international environmental laws and regulations and is exposed to the costs and risks of registering, handling, processing, storing, transporting, and disposing of hazardous substances, especially lead and acid. The Company’s operations are also subject to federal, state, local and international occupational safety and health regulations, including laws and regulations relating to exposure to lead in the workplace.

The Company is responsible for certain cleanup obligations at the former Yuasa battery facility in Sumter, South Carolina, that predates its ownership of this facility. This manufacturing facility was closed in 2001 and the Company established a reserve for this facility, which was $1,060 as of October 4, 2020 and March 31, 2020. Based on current information, the Company’s management believes this reserve is adequate to satisfy the Company’s environmental liabilities at this facility. This facility is separate from the Company’s current metal fabrication facility in Sumter.

Lead and Foreign Currency Forward Contracts

To stabilize its lead costs and reduce volatility from currency movements, the Company enters into contracts with financial institutions. The vast majority of such contracts are for a period not extending beyond one year. Please refer to Note 7 - Derivative Financial Instruments for more details.

Exit Charges

During fiscal 2021, the Company committed to a plan to close its facility in Vijayawada, India to align with its strategic vision for the new line of business structure and footprint. The Company recorded exit charges of $1,509, primarily relating to asset write-offs.

During fiscal 2019, the Company committed to a plan to close its facility in Targovishte, Bulgaria, which produced diesel-electric submarine batteries. Management determined that the future demand for batteries of diesel-electric submarines was not sufficient given the number of competitors in the market. Of the estimated total charges of $30,000 for all these actions, the Company had recorded charges amounting to $20,242 in fiscal 2019, relating to severance and inventory and fixed asset write-offs and an additional $5,123 relating to cash and non-cash charges during fiscal 2020. During the six months of fiscal 2021, in keeping with its strategy of exiting the manufacture of batteries for diesel-electric submarines, the Company continued to execute further actions which resulted in a non-material net impact from the cash and non-cash charges.

During the second quarter of fiscal 2020, in keeping with its strategy of exiting the manufacture of batteries for diesel-electric submarines, the Company also sold certain licenses and assets for $2,031 and recorded a net gain of $892, which were reported as other exit charges in our Specialty segment.

During the second quarter of fiscal 2020, the Company also wrote off $5,441 of assets at its Kentucky and Tennessee Motive Power plants, as a result of its strategic product mix shift from traditional flooded batteries to maintenance free lead acid and lithium batteries.

Richmond, Kentucky Plant Fire

In fiscal 2020, a fire broke out in the battery formation area of the Company's Richmond, Kentucky motive power production facility. The Company maintains insurance policies for both property damage and business interruption and are finishing cleanup and repair. The Company is nearing completion of the reconstruction of the facility and estimates that the total claim, including the replacement of inventory and equipment, the cleanup and repairs to the building, as well as the claim for business interruption is approximately $45,000.

In fiscal 2020, the Company recorded $17,037 of write-offs for damages caused to its fixed assets and inventories, as well as for cleanup, asset replacement and other ancillary activities directly associated with the fire and received $12,000 in advances related to its initial claims for recovery from its property and casualty insurance carriers.

During the six months of fiscal 2021, the Company recorded a further charge of $15,316 for cleanup and received $18,144 in advances from the insurance carriers. Accumulated charges relating to the fire through October 4, 2020 were $32,353 and advances received from the property and casualty insurance carriers were $30,144.

The Company also received $10,156 through October 4, 2020, of which $5,156 was recorded in the six months of fiscal 2021 and $5,000 in fiscal 2020, relating to a partial settlement of its claim for business interruption which was recorded as a reduction to cost of goods sold. The Company expects to receive $2,000 in its third quarter of fiscal 2021 which would complete the settlement of its business interruption claim.

The 2023 Notes are fully and unconditionally guaranteed, jointly and severally, by certain of its subsidiaries that are guarantors under the Amended Credit Facility. These guarantees are unsecured and unsubordinated obligations of such guarantors.

2017 Credit Facility and Subsequent Amendment

In fiscal 2018, the Company entered into a credit facility (the “2017 Credit Facility”). The 2017 Credit Facility scheduled to mature on September 30, 2022, initially comprised a $600,000 senior secured revolving credit facility (“2017 Revolver”) and a $150,000 senior secured term loan (“2017 Term Loan”). The Company utilized the borrowings from the 2017 Credit Facility to repay its pre-existing credit facility.

In fiscal 2019, the Company amended the 2017 Credit Facility (as amended, the “Amended Credit Facility”) to fund the Alpha acquisition. The Amended Credit Facility consists of $449,105 senior secured term loans (the “Amended 2017 Term Loan”), including a CAD 133,050 ($99,105) term loan and a $700,000 senior secured revolving credit facility (the “Amended 2017 Revolver”). The amendment resulted in an increase of the 2017 Term Loan and the 2017 Revolver by $299,105 and $100,000, respectively.

As of October 4, 2020, the Company had $53,000 outstanding under the Amended 2017 Revolver and $393,665 under the Amended 2017 Term Loan.

Subsequent to the amendment, the quarterly installments payable on the Amended 2017 Term Loan are $5,645 beginning December 31, 2018, $8,468 beginning December 31, 2019 and $11,290 beginning December 31, 2020 with a final payment of $320,000 on September 30, 2022. The Amended Credit Facility may be increased by an aggregate amount of $325,000 in revolving commitments and / or one or more new tranches of term loans, under certain conditions. Both the Amended 2017 Revolver and the Amended 2017 Term Loan bear interest, at the Company's option, at a rate per annum equal to either (i) the London Interbank Offered Rate (“LIBOR”) or Canadian Dollar Offered Rate (“CDOR”) plus (i) LIBOR plus between 1.25% and 2.00% (currently 1.50% and based on the Company's consolidated net leverage ratio) or (ii) the U.S. Dollar Base Rate (which equals, for any day a fluctuating rate per annum equal to the highest of (a) the Federal Funds Effective Rate plus 0.50%, (b) Bank of America “Prime Rate” and (c) the Eurocurrency Base Rate plus 1%; provided that, if the Base Rate shall be less than zero, such rate shall be deemed zero) (iii) the CDOR Base Rate equal to the higher of (a) Bank of America “Prime Rate” and (b) average 30-day CDOR rate plus 0.50%. Obligations under the Amended Credit Facility are secured by substantially all of the Company’s existing and future acquired assets, including substantially all of the capital stock of the Company’s United States subsidiaries that are guarantors under the Amended Credit Facility and up to 65% of the capital stock of certain of the Company’s foreign subsidiaries that are owned by the Company’s United States subsidiaries.

The Amended Credit Facility allows for up to two temporary increases in the maximum leverage ratio from 3.50x to 4.00x for a four quarter period following an acquisition larger than $250,000. Effective December 7, 2018 through December 28, 2019, the maximum leverage ratio was increased to 4.00x. On December 29, 2019, the maximum leverage ratio returned to 3.50x.

The current portion of the Amended 2017 Term Loan of $44,990 is classified as long-term debt as the Company expects to refinance the future quarterly payments with revolver borrowings under the Amended Credit Facility.

Short-Term Debt

As of October 4, 2020 and March 31, 2020, the Company had $31,813 and $46,544, respectively, of short-term borrowings. The weighted average interest rate on these borrowings was approximately 2% at October 4, 2020 and 3% at March 31, 2020.

Letters of Credit

As of October 4, 2020 and March 31, 2020, the Company had standby letters of credit of $7,720.

Debt Issuance Costs

Amortization expense, relating to debt issuance costs, included in interest expense was $518 and $374, respectively, for the quarters ended October 4, 2020 and September 29, 2019 and $1,036 and $752 for the six months ended October 4, 2020 and September 29, 2019. Debt issuance costs, net of accumulated amortization, totaled $7,457 and $8,493, respectively, at October 4, 2020 and March 31, 2020.

Segment Reporting [Abstract]

Business Segments

Business Segments

Effective April 1, 2020, the Company's chief operating decision maker, or CODM (the Company's Chief Executive Officer), changed the manner in which he reviews financial information for purposes of assessing business performance and allocating resources, by focusing on the lines of business on a global basis, rather than on geographic basis. As a result of this change, the Company re-evaluated the identification of its operating segments and reportable segments and identified the following as its three new operating segments, based on lines of business:

•Energy Systems - uninterruptible power systems, or “UPS” applications for computer and computer-controlled systems, as well as telecommunications systems, switchgear and electrical control systems used in industrial facilities and electric utilities, large-scale energy storage and energy pipelines. Energy Systems also includes highly integrated power solutions and services to broadband, telecom, renewable and industrial customers, as well as thermally managed cabinets and enclosures for electronic equipment and batteries.

•Motive Power - power for electric industrial forklifts used in manufacturing, warehousing and other material handling applications, as well as mining equipment, diesel locomotive starting and other rail equipment; and

•Specialty - premium starting, lighting and ignition applications in transportation, energy solutions for satellites, military aircraft, submarines, ships and other tactical vehicles, as well as medical and security systems.

The new operating segments also represent the Company's reportable segments under ASC 280, Segment Reporting. All prior comparative periods presented have been recast to conform to these changes.

Summarized financial information related to the Company's reportable segments for the second quarter and six months ended October 4, 2020 and September 29, 2019, is shown below:

	Quarter ended				Six months ended

Total operating earnings (1)	$	55,415	$	58,710	$	108,635	$	127,046

(1) The Company does not allocate interest expense or other (income) expense to the reportable segments.

(2) The Company does not identify or allocate assets by reportable segment, nor does the CODM evaluate reportable segments using discrete asset information.

(3) Reportable segments do not record inter-segment revenues and accordingly there are none to report.

Goodwill

Concurrent with the change in reporting segments effective April 1, 2020, goodwill was reassigned to the affected reporting units that have been identified within each operating segment, using a relative fair value approach outlined in ASC 350, Intangibles - Goodwill and Other.

The following table presents the amount of goodwill that has been reassigned to each of the Company's reportable segments as of April 1, 2020, using the relative fair value approach, as well as any changes in the carrying amount of goodwill by segment during the six months of fiscal 2021:

Subsequent Events

Subsequent Events

On November 10, 2020, the EnerSys’ Board of Directors approved a plan to substantially close its facility in Hagen, Germany, which produces flooded motive power batteries for forklifts. EnerSys expects to incur a pre-tax charge of approximately $82,000 under this plan when completed, the majority of which is expected to be recorded by the end of fiscal 2021, of which $20,000 is expected to be a non-cash charge from inventory and equipment write-offs. Cash charges include severance, clean up and decommissioning related to the facility, contractual releases and legal expenses.

Management determined that future demand for the motive power batteries produced at this facility was not sufficient, given the conversion from flooded to maintenance free batteries by customers, the existing number of competitors in the market as well as the near term decline in demand and increased uncertainty from the ongoing pandemic.

In connection with this restructuring plan, which is estimated to be substantially complete in fiscal 2022, EnerSys estimates that there will be a reduction of approximately 200 employees.

On November 10, 2020, the Board of Directors approved a quarterly cash dividend of $0.175 per share of common stock to be paid on December 31, 2020, to stockholders of record as of December 18, 2020.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments except those otherwise described herein) considered necessary for a fair presentation have been included, unless otherwise disclosed. Operating results for the three and six months ended October 4, 2020 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2021.

The Consolidated Condensed Balance Sheet at March 31, 2020 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.

The financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s 2020 Annual Report on Form 10-K (SEC File No. 001-32253), which was filed on June 1, 2020 (the “2020 Annual Report”).

EnerSys (the “Company,”) reports interim financial information for 13-week periods, except for the first quarter, which always begins on April 1, and the fourth quarter, which always ends on March 31. The four quarters in fiscal 2021 end on July 5, 2020, October 4, 2020, January 3, 2021, and March 31, 2021, respectively. The four quarters in fiscal 2020 ended on June 30, 2019, September 29, 2019, December 29, 2019, and March 31, 2020, respectively.

The consolidated condensed financial statements include the accounts of the Company and its wholly-owned subsidiaries and any partially owned subsidiaries that the Company has the ability to control. All intercompany transactions and balances have been eliminated in consolidation.

Recently Adopted Accounting Pronouncements and Accounting Pronouncements Issued But Not Yet Adopted

Recently Adopted Accounting Pronouncements

In June 2016, the FASB, issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326)”: Measurement of Credit Losses on Financial Instruments, which changes the recognition model for the impairment of financial instruments, including accounts receivable, loans and held-to-maturity debt securities, among others. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In contrast to current guidance, which considers current information and events and utilizes a probable threshold, (an “incurred loss” model), ASU 2016–13 mandates an “expected loss” model. The expected loss model: (i) estimates the risk of loss even when risk is remote, (ii) estimates losses over the contractual life, (iii) considers past events, current conditions and reasonable supported forecasts and (iv) has no recognition threshold. The Company adopted the standard effective April 1, 2020 and the adoption did not have a material impact on the Company's operating results, financial position or cash flows. However, the adoption resulted in the modification of the Company's policies for accounts receivable.

The Company estimates the allowance for credit losses in relation to accounts receivable based on relevant qualitative and quantitative information about historical events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported accounts receivable. Subsequent to April 1, 2020, accounts receivable are recorded at amortized cost less an allowance for expected credit losses. The Company maintains an allowance for credit losses for the expected failure or inability of its customers to make required payments. The Company recognizes the allowance for expected credit losses at inception and reassesses quarterly, based on management’s expectation of the asset’s collectability. The allowance is based on multiple factors including historical experience with bad debts, the credit quality of the customer base, the aging of such receivables and current macroeconomic conditions, as well as management’s expectations of conditions in the future. The Company’s allowance for uncollectible accounts receivable is based on management’s assessment of the collectability of assets pooled together with similar risk characteristics. The Company then adjusts the historical credit loss percentage by current and forecasted economic conditions. The Company then includes a baseline credit loss percentage into the historical credit loss percentage for each aging category to reflect the potential impact of the current and economic conditions. Such a baseline calculation will be adjusted further if changes in the economic environment impacts the Company's expectation for future credit losses.

The following table sets forth the quarterly changes in the Company's allowance for doubtful accounts:

Allowance for doubtful accounts:	Balance at Beginning of Period		Provision for doubtful debts		Write-offs, net of recoveries and other		Balance at End of Period
First quarter ended July 5, 2020	$	15,246	$	96	$	(2,113)	$	13,229
Second quarter ended October 4, 2020	$	13,229	$	86	$	2	$	13,317

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848)”: Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional expedients to ease the financial reporting burdens of the expected market transition from London Interbank Offered Rate (LIBOR) to an alternative reference rate such as Secured Overnight Financing Rate (SOFR). The Company’s agreements with respect to its borrowings already contain comparable alternative reference rates that would automatically take effect upon the phasing out of LIBOR. The Company has adopted the standard and the adoption did not have a material impact on the Company's consolidated financial statements.

Accounting Pronouncements Issued But Not Adopted as of October 4, 2020

In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740)”: Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently assessing the potential impact that the adoption will have on its consolidated financial statements.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions take into account historical and forward looking factors that the Company believes are reasonable, including, but not limited to, the potential impacts arising from the coronavirus pandemic of 2019 (“COVID-19”) and public and private sector policies and initiatives aimed at reducing its transmission. As the extent and duration of the impacts of COVID-19 remain unclear, the Company’s estimates and assumptions may evolve as conditions change. Actual results could differ significantly from those estimates.

Examples of significant estimates include the allowance for credit losses, the recoverability of property, plant and equipment, the incremental borrowing rate for lease liabilities, the recoverability of intangible assets and other long-lived assets, fair value measurements, including those related to financial instruments, goodwill and intangible assets, valuation allowances on tax assets, pension and postretirement benefit obligations, contingencies and the identification and valuation of assets acquired and liabilities assumed in connection with business combinations.
